Hello everybody,

I did a test on Si and got for example the following optical eigenvector:
     freq (    4) =      15.673472 [THz] =     522.810745 [cm-1]
 (  0.000000   0.000000     0.707107   0.000000     0.000000   0.000000   )
 (  0.000000   0.000000    -0.707107   0.000000     0.000000   0.000000   )

Can you tell me if the coordinates of the eigenvectors are cartesian or crystal, please? Apologize if the question is trivial, I'd daresay they're cartesian but I couldn't find the info in any doc and I am not sure about...


Thanks in advance
Patrizio
